Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy. When testing rubbers for impact brittleness use Test Method D Test temperatures, number of failures and the determined brittleness temperature.

When testing plastic sheeting for impact brittleness, use Test Method D Assurance Enabling you to identify and mitigate the intrinsic zstm in your operations, supply chains and business processes.
A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection. Send us a request Need help or have a question? It does not, necessarily, determine the lowest temperature at which the subject material may be used.
All purchase orders must be postmarked or recieved no later than January 5 thto qualify.
CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror d74. CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel.
This test method has been found useful for specification purposes, but does not necessarily measure the lowest temperature at which the material is suitable for use. Formally confirming that your products and services meet all trusted external and internal standards.
Send us a request Wilton UK: There are three specimens: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. However, this holds only under conditions in which the material is subjected to deformations similar to those imposed in the test. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

The specimen holder is lowered into a bath at a specified temperature. The brittleness temperature is determined by immersing the specimens in the specimen holder in a bath containing a heat transfer that is cooled, usually by liquid nitrogen, carbon dioxide, or powdered dry ice, to a predetermined temperature for a period of three minutes.
ASTM D employs three cutting dies: Link to Active This link will always route to the current Active version of the standard. The test provides for the evaluation of long-time effects such as crystallization, or those effects that are introduced by low-temperature incompatibility of c746 in the material s746 test. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Plastics and elastomers are used in many applications requiring low-temperature flexing with or without impact. Historical Version s – view previous versions of standard.
Brittleness Temperature ASTM D746 ISO 974
The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures. The procedure is repeated at a lower temperature until enough data is aatm to determine a brittleness temperature.
Need help or have a question? D46 data obtained by this method to predict the behavior of plastic and elastomeric materials at low temperatures only in applications in which the conditions of deformation are similar to those specified in this test method. The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service life. Brittle failure is s746 by ASTM D as fracture into 2 or more pieces, or any crack visible to the d7446 eye.
This test provides for the evaluation of long term effects, such as crystallization, or the incompatibility of material borne plasticizers when subjected to subnormal temperatures. It is utilized primarily for plastics and elastomers. Standards can be obtained from appropriate standards authorities. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Assurance Testing Inspection Certification.
